Welcome to the PIP data revisions page. This site tracks the revisions that have been made to the data in the World Bank’s Poverty and Inequality Platform (PIP).

In a typical year, there are two major updates (in March/April and September/October), which bring in new survey data. These major updates are documented using a What’s New document (published in the Global Poverty Monitoring Technical Notes series). When necessary, intermediate updates are made to correct errors as soon as possible. Changes made as part of the intermediate updates are documented in this site.

Go to Data Updates at the top of this page to see a comprehensive record of all the changes, updates, and corrections to the PIP data.
